5.6 DASDCAT (Display PDS datasets and members)

5.6.1 Function

The DASDCAT utility displays PDS datasets and members from a DASD image file. It can generate a list
of members in a given PDS dataset or can list the contents of a single member or all members in a PDS.

5.6.3
Parameter

-i image

The name (and optionally path) of the DASD image file.

shadowfile

The (optional) name of an associated shadow DASD file.

pdsname

The name of the partitioned dataset from which information will be extracted.

spec

spec can be one of the following:

- The name of a PDS member to be listed.

- An asterisk (“*”), meaning that all members in the PDS are to be listed.

- A question mark (“?”) which causes the list of members in the PDS to be returned.

flags

flags can be one of the following:

- “c” (list the member(s) as card images)

- “a” (list the member(s) in ASCII)

If no arguments are given the program displays help text and exits.
